BOILER.

SPECIFICATION forming part of Letters Patent No. 644,862, dated March 6,1900. Application filed May 6, 1899. Serial No. 716,824. (No model.)

To ctZZ whom it vita/y concern:

Be it known that we, DAVID S. JACOBUS and MARTIN R. J ACOBUS, citizensof the United States, residing at Ridgefield, in the county of Bergenand State of New Jersey, have invented certain new and usefulImprovements in Steam Heating Boilers, of which the following is aspecification.

Our invention has reference to improvements in steam-heating boilers ofthe types generally used for heating dwellings, apartments, &c., inwhich a comparativelysmall quantity of water is contained in thewaterspace.

This invention refers to improvements in the constructions described inour prior ap plications, Serial No. 702,631, filed January 19, 1899, andSerial No. 705,535, filed February 15, 1899, in which we combined with asteam-heating boiler or similar apparatus a water supply and receiving,vessel connected below the water-level with the water-space of theboiler and above the water-level with the steam-space of the boiler forthe purpose of establishing a substantially-perm anent waterlevel.

In boilers ot' the type in which-we desire to use our improvementsconsiderable trouble is caused by the water being driven out of theboiler in starting up the fire and frequently during the regularoperation of the heating apparatus, thus causing the boiler to beWeakened by excessive heating or rendered useless by being burned out,or, if an ordinary automatic feeding device is used, the water whichreturns from the heating system will sometimes flood the boiler. 1naddition to these difficulties the water which is driven out of theboiler will sometimes cause trouble by producing a water-hammer andpounding in the steam-pipes.

It is the object of our present invention to overcome these objectionsby providing, in addition to a water supply and receiving vessel, aseparator connected with said supply and receiving vessel below thewater-level therein and also with the steam-space of the boiler. Fromthis separator the main to the radiators, 300., is led.

The nature of our invention will best be understood when described inconnection with the accompanying drawings, in which- Figure 1 representsa perspective view of I a steam-heating boiler provided with ourimprovements. Fig. 2 is a vertical section thereof, part being brokenaway. Fig. 3 is a vertical section, partly in elevation, illustrating amodified form for the separator.

Similar letters and numerals of reference designate corresponding partsthroughout the several views of the drawings.

. Referring to the drawings, the letter A designates a steam-heatingboiler of any usual well-known construction, to which our improvement isapplied. In connection with said boiler we make use of a water supplyand receiving vessel B, which may be of any suitable form and ispreferably placed at such a height as to be about one-half full at theordinary level of the boiler A. The capacity of this vessel is such asto supply the proper amount of water in case of a sudden diminution, asin starting up the fire, or from other causes which would affect thewater-level in the boiler. The vessel B is connected at or near itsbottom or lower portion with the water-space 1 of the boiler, as by asuitable pipe 2, connecting with the return-pipe R from the radiators.Steam is conducted from the steam-space of the boiler by means of asuitable pipe connection 3 to the upper portion or what may be termedthe steamspace of the vessel- B. A suitable pipe connection '7 is madebetween the water-space 1 of the boiler A and the water-space 8 of thevessel B for establishing a water circulation between the water in thevessel B and the water in the boiler.

The construction so far described is substantially that shown anddescribed in our prior application, Serial No. 705,535; but instead ofdrawing the steam from the steamspace in the Water vessel as supplied bythe pipe 3 we provide an external separator S, which is connected withthe steam-space of the boiler by a pipe connection 9, having adownwardly-turned terminal 10 within said separator S. The steam sointroduced into the separator passes out at the top of said separatorthrough the steam-main 5, con nected with said separator in a usualmanner. The lower portion of said separator is connected with the watersupply and receiving vessel by means of a vertical pipe 11,

which extends to nearthe bottom of said vessel, so as to be below thewater-level within said vessel. In consequence of this construction anywater which may be carried up from the boiler through the pipeconnection 9 separates in the separator and passes into the supply andreceiving vessel B, while substantially-dry steam passes upwardlythrough the separator and to the main 5, from whence it is distributedto the radiators. The separator S may be constructed in the form shownin Fig. 3, where it is extended directly into the supply and receivingvessel B, instead of making use of the pipe 11. This may be done byeither threading the separator and screwing it directly into the vesselor by making it in two parts and inserting the lower part 8 from theinterior of the vessel in a Well-known manner.

What we claim as new is 1. The combination with a steam-heating boiler,of a water supply and receiving vessel located at a level with respectto the boiler to be only partially filled with water at all times andsaid vessel being connected below the water-level with the water-spaceof the boiler and above the water-level with the steam-space of theboiler, aseparatorhaving a connection with the water supply and receiving vessel below its water-level and a connection with the steam-space ofthe boiler, and a steam-main connected with said separator,substantially as described.

2. The combination with a steam-heating boiler, of a water supply andreceiving vessel located at a level with respect to the boiler to beonly partially filled with water at all times and said vessel beingconnected below the water-level with the water-space of the boiler andabove the water-level with the steam-space of the boiler and alsoconnected at another level with the Water-space of the boiler so as toinduce circulation of water, a separator having a connection with thewater supply and receiving vessel below its waterlevel and a connectionwith the steam-space of the boiler, and a steam-main connected with saidseparator, substantially as described.

3. The combination with a steam-heating boiler, of a water supply andreceiving vessel located ata level with respect to the boiler to be onlypartially filled with water at all times and said vessel being connectedbelow the water-level with the water-space of the boiler and above thewater-level with the steam-space of the boiler, a separator having aconnection with the water supply and receiving vessel below itswater-level, asteammain connected with the top of said separator, and aconnection with the steam-space of the boiler and said separatorarranged intermediate of its connection with the steammain and itsconnection with the water supply and receiving vessel, substantially asdescribed.

4. The combination with a steam-heating boiler, of a water supply andreceiving vessel located-at a levelwith respect to the boiler to be onlypartially filled with water at all times and said vesselbeing connectedbelow the water-level with the water-space of the boiler and above thewater-level with the steam-space of the boiler, a separator having aconnection with the water supply and receiving vessel below itsWater-level and a conuection with the steam-space of the boiler having adownwardly-turned discharge end in said separator, and a steam-mainconnected with said separator, substantially as described.

5. The combination with a steam-heating boiler, of a water supply andreceiving ves sel located at a level with respect to the boiler to beonly partially filled with water at all times and said vessel beingconnected below the water-level with the water-space of the boiler andabove the water-level with the steam-space of the boiler, a separatorhaving a connection with the water supply and receiving vessel below itswater-level, a discharge-opening for steam at the top of said separator,and a connection with the stea1nspace of the boiler and said separatorarranged intermediate of its connection with the steam-main and itsconnection with the Water supply and receiving vessel, substantially asdescribed.

In testimony whereof we have hereunto set our hands in the presence oftWo subscribing witnesses.
